Failsoft Operation; Smartnet/Smartzone Scanning; Dynamic Regrouping - E.F. Johnson Company 5100 Series Operating Manual

"EMERGNCY" is indicated in the display for 3
seconds.
2. To place the emergency call, manually press the
PTT switch and begin speaking as with a standard
call. All group calls which follow are then emer-
gency calls (private, telephone, and call alert calls
are not allowed). If the channel is changed, the call
is made on the emergency talk group programmed
for the new channel.
3. To exit this mode, power must be turned off.

Failsoft Operation

If a failure occurs in the SMARTNET/Smart-
Zone system so that it cannot be used, the transceiver
automatically enters the failsoft mode. When in this
mode, "FAILSOFT" and the alias of the selected
channel are alternately displayed.
When in the failsoft mode, operation is in the
conventional mode on the preprogrammed failsoft
channel (a different failsoft channel can be
programmed on each talk group). If a transmission is
attempted before a failsoft channel is located, a contin-
uous tones sounds until the PTT switch is released.
When the radio system returns to normal operation,
this is automatically detected and normal operation
resumes.

SMARTNET/SmartZone Scanning

Scanning on a SMARTNET/Smartzone system is
called Priority Monitor Scan, and is similar to the stan-
dard scanning described starting on page 13. Each
SMARTNET/SmartZone system can be programmed
with up to as many scan lists as can be stored in
memory, and each list can include up to 16 channels
from the same SMARTNET/SmartZone system, one
of which can be a priority channel. The priority
channel can also be the selected channel.
One of these lists can then be selected by each
SMARTNET channel. In addition, if the Scan (List)
Select option key or menu parameter is programmed,
the scan list selected by all talk groups in the current
system can be temporarily changed. The procedure is
described on page 15. The default scan list for all
groups is reselected on power-up.
SMARTNET/SMARTZONE FEATURES
SMARTNET/SmartZone lists are also user
programmable if the Scan Edit option key is
programmed. In addition, nuisance channels can be
temporarily deleted (see page 13).
Scanning is enabled and disabled by the Scan
option key or menu parameter. Also, channels can be
programmed so that scanning is automatically disabled
or automatically starts whenever the channel is
selected. If scanning is enabled and the selected channel
does not permit scanning, it automatically resumes
when a channel is selected that permits scanning.
In addition to calls on channels in the scan list,
pages, private calls, and telephone calls are received
while scanning. Priority talk groups can be designated,
and messages on those talk groups are received while
listening to lower priority messages. However, private
and telephone calls are not interrupted by priority
messages.
When responding to calls in the scan mode,
programming determines if the response always
occurs on the talk group of the call or the Selected
Group if they are different. Transmissions at other
times always occur on the selected talk group.

Dynamic Regrouping

The dynamic regrouping feature allows a
dispatcher to switch mobiles to a predefined
regrouping channel to receive an important message.
Dynamic regrouping operates as follows:
1. When this command is received, alternating tones
sound for 5 seconds and the transceiver automati-
cally changes to the regrouping channel and the
display indicates the alias of the channel.
2. Manually select the channel corresponding to that
alias. If this is not done, transmission still occurs on
the new channel, but the alternating tones sound
each time the PTT switch is pressed.
3. Talk and listen as usual. The dispatcher will cancel
dynamic regrouping. If a standard channel is not
selected after this occurs, an error tone periodically
sounds.
